When applying a "reasonably safe" test, what factors should courts consider to determine whether a product design is reasonably safe? Plaintiff collided into an automobile while riding a motorcycle manufactured and designed by the defendant. Consequently, the plaintiff suffered serious leg injuries. The evidence suggested that the plaintiff's leg injuries would have been mitigated or avoided completely had the defendant incorporated "crash bars" into the design of the motorcycle. The plaintiff sued for the alleged design defect, along with an alleged failure to warn buyers of the existence of injury-mitigating crash bars.
